I have a Fuji Feather, and i Absolutely love it. Its definitely not the lightest bike in the world, but coming from a old 80's steel beater, this thing feels like a...feather.. I have read lots of people griping about the weight, but it really doesn't bother me at all.
Ride quality is fantastic and i really only notice the road on the very worst sections.
I'm rocking 700x23's right now, i could easily go up to 25's, i'm not sure if 28's would fit. But i have no interest is going higher than 25.
The wheels themselves are a bit heavy, but very durable. I upgraded mine about a month ago, but i wouldnt say its immediately necessary. I used the money i saved on the frame and when a sale on Nashbar/Velomine came around i picked up a new set for cheap.
Its as fast as you are strong, very responsive handling too.
